TA8252H fiche technique
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8252H
Max Power 37W BTL × 4ch Audio Power IC
The TA8252H is 4ch BTL audio power amplifier for car audio
application.
This IC can generate more high power: POUT MAX = 37W
as it is included the pure complementary PNP and NPN
transistor output stage.
It is designed low distortion ratio for 4ch BTL audio power
amplifier,builtin standby function, muting function,clip
detector,and diagnosis circuit.
Additionally, the AUX.amplifier is builtin, it can make the beep
signal etc.output to 2 channnels (out 1 and 4).It contains various
kind of protectors for car audio use.
Features
Weight: 9.8g (typ.)
· High power
: POUT MAX (1) = 37W (typ.)
(VCC = 14.4V, f = 1kHz, EIAJ max., RL = 4)
: POUT MAX (2) = 35W (typ.)
(VCC = 13.7V, f = 1kHz, EIAJ max., RL = 4)
: POUT (1) = 24W (typ.)
(VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4)
: POUT (2) = 21W (typ.)
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4)
· Builtin clip detector & diagnosis circuit.(pin(25))
· Low distortion ratio: THD = 0.02% (typ.)
(VCC = 13.2V, f = 1kHz, POUT = 5W, RL = 4)
· Low noise: VNO = 0.10mVrms (typ.)
(VCC = 13.2V, Rg = 0, GV = 26dB, BW = 20~20kHz)
· Builtin standby switch function (pin(2))
· Builtin multing function (pin(24))
· Builtin AUX. amplifier from single input (pin(16)) to 2 channels output; out1 and 4
· Builtin various protection circuit
: Thermal shut down, Over voltage, Out to GND, Out to VCC, Out to Out short.
· Operating supply voltage: VCC (opr) = 9~18V
